The pure CuS and Mn2+ doped CuS nanoparticles are synthesized by wet chemical route. The CuS phase and hexagonal crystal structure is confirmed by the powder X-ray diffraction and Raman analysis. The vibrational bonds present in the respective synthesized samples are confirmed by Fourier transformed infra-red spectroscopy. The spherical shapes of the nanoparticles are validated by the electron diffraction in scanning and transmission mode. The thermal analysis showed the Mn2+ doped CuS nanoparticles to be more stable than pure CuS nanoparticles. The thermal parameters determined using Coats-Redfern relation stated thermal activation energy and enthalpy change values are highest in the higher temperature range. The Seebeck coefficient variation with temperature and ambient condition Hall effect measurements showed the synthesized nanoparticles to be semiconducting and p-type in nature. The magnetic properties study by Gouy method showed the nanoparticles to be paramagnetic.

纯掺杂和锰掺杂的硫化铜(CuS)纳米颗粒的比较研究

通过湿化学法合成了纯CuS和Mn 2+掺杂的CuS纳米颗粒。通过粉末X射线衍射和拉曼分析证实了CuS相和六方晶体结构。存在于各个合成样品中的振动键通过傅立叶变换红外光谱法确认。纳米粒子的球形通过扫描和透射模式下的电子衍射验证。热分析表明Mn 2+掺杂的CuS纳米粒子比纯CuS纳米粒子更稳定。使用Coats-Redfern关系确定的热参数表示热活化能和焓变值在较高温度范围内最高。塞贝克系数随温度和环境条件霍尔效应的变化而变化,表明合成的纳米粒子本质上是半导体和p型的。通过Gouy方法进行的磁性研究表明,纳米粒子是顺磁性的。
